CARBON-REIVIOVING IMPLEMEIXI'T.
Application filed September 21, 1928. Serial No. 136,814.
My present invention relates to an improved carbon removing implement espe cially adapted for use in cleaning or scraping the walls of packing grooves of pistons of internal combustion engines.
The primary object of the invention is the provision of an improved tool or implement which is manually operated for this purpose, which is simple in construction and operation, may be manipulated with facility, is adjustable for cleaning grooves of various sizes, and which may be manufactured at a comparatively low cost of production.
The invention consists in certain novel combinations and arrangements of parts including a resilient yoke or handle and scraper-holder having an interchangeable scraper head, as will hereinafter be more fully'set forth and claimed.
In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to one mode Ihave thus far devised for the practical application of the principles of my invention.
Figure 1 is a plan View of the device with parts broken away for convenience of illustration showing its relation to a grooved piston.
' Figure 2 is a view in side elevation of a piston with the implement applied thereto in operative position.
Figure 3 is a detail plan view of the interchangeable scraper head.
Figure 4 is an edge view of the scraper head showing the various sizes of scraper blades thereon, and the detached fastening screw.
In order that the utility and operation of the implement in its relation to the piston 1 may readily be understood I have shown in Figures 1 and 2 the grooves 2 in the piston which are usually employed for receiving the packing rings of the piston.
The manually operated implement or tool is preferablyfashioned of resilient metal in the general shape or form of a yoke of U- shape having a handle 3 which possesses resiliency for clasping the tool about the grooved piston. One portion of the handle 3 merges into an integral jaw 4 which is curved to conform to the annular grooves of the piston, and is disposed in a plane at right angles to the handle by twisting the material, as indicated. The jaw is formed with an extension handle 5, which is broken away in Figure 1 for convenience of illustration, to be'grasped by the hand when manipulating the tool in. its operative position-as shown in Figures 1 and 2.
The other arm oftheyoke-handle 3 is l fashioned with a tool holder 6 which also curves to conform to the periphery of the piston and is twisted into a plane at right angles to the plane of the material of the handle 3. 6 thus present their curved edges to the piston wien the tool or implement is disposed about'the piston. The resiliency of the spring handle 3 permits the jaw and holder to be spread apart suificiently so that the tool may be passed around the piston to the position indicated in Figure 1 with. the inner edge Of the jaw 4: in a groove and in frictional contact with its vertical wall.
The tool holder is slotted near its end at 7 as best seen in Figure 1 for co-action in retaining the scraper head in place on the holder. The scraper head isa metal plate 8 of cruciform shape and provided with a central screw or bolt hole 9 to receive the fastening screw 10 which passes through anopening in the holder 6 and is threaded into the head. The head is located beneath the end of the holder and lies fiat against the side of the arm, being drawn tightly thereagainst by the fastening screw.
On the head are fashioned a number of scraper blades, as 11, 12, 13, and 14, which vary in size to adapt them to various sizes of packing grooves in the pistons of standard make, and each blade is of .a size to be inserted in the locking groove or slot 7 of the tool holder 6.
Thus a selected blade corresponding to the size of the groove to be cleaned or scraped of carbon is turned to position to engage the groove and one of the other blades is slipped through the locking slot 7. Then the fastening screw is tightened to draw the head against the holder and the blade in the slot is utilized to take the strain on the head as the implement is utilized. WVith the implement in the position indicated in Figure 1 the handle 8 may be grasped in one hand and the extension handle 5 grasped in the other hand with the guide jaw 4 located in the groove opposite to the point of contact of the scraper bladewith the wall of the groove to be cleaned. The implement or tool is then turned about theaxis of.
The curved jaw 4t and the holder the piston, the blade scrapin along on the surface of the groove wills to clear or clean off any carbon or other deposits in the groove. The guide jaw holds the implement in operative position and the power is applied by the use of the hands in manipulating the implement about the piston.
Nhile the jaw retains-the implement on the piston with sufficient friction to prevent its accidental displacement, such friction is not sufficient to prevent removal of the implement, and it may be withdrawn from the piston by a pull on the handle 3, after the groove has been cleaned or scraped.
the slot in the head of the tool holder for 25 locking the head, and a screw for fastening the head to the holder.
In testimony whereof I aiiix my signature.
